[Relationship of cerebrospinal fluid and serum levels of SIL-2R, eNOS, and CD93 with the progression and prognosis of viral encephalitis in children].

Objectives: To investigate the relationship of cerebrospinal fluid and serum levels of soluble interleukin-2 receptor (SIL-2R), endothelial nitric oxide synthase (eNOS), and cluster of differentiation 93 (CD93) with the progression and prognosis of viral encephalitis (VE) in children.

Methods: Prospectively, 102 children with VE admitted from January 2021 to January 2024 were selected as the VE group. The patients were divided into a mild subgroup (64 patients) and a severe subgroup (38 patients) according to disease progression. The patients were also divided into a good prognosis subgroup (29 patients) and a poor prognosis subgroup (73 patients) according to prognosis. A control group of 102 children with central nervous system diseases who were examined and found not to have VE during the same period was selected. The factors contributing to the poor prognosis of children with VE and the predictive value of SIL-2R, eNOS, and CD93 in cerebrospinal fluid and serum for the poor prognosis of children with VE were evaluated.

Results: Cerebrospinal fluid and serum SIL-2R, eNOS, and CD93 levels were significantly increased in the VE group, severe subgroup, and poor prognosis subgroup (<0.05). Multivariate logistic regression analysis showed that high SIL-2R, eNOS, and CD93 levels in cerebrospinal fluid and serum were risk factors for poor prognosis in children with VE (<0.05). Receiver operating characteristic curve analysis showed that the combination of cerebrospinal fluid SIL-2R, eNOS, and CD93 was superior to these individual indicators in prediction of poor prognosis in children with VE (<0.05). Similarly, the combination of serum SIL-2R, eNOS, and CD93 was superior to these individual indicators in prediction of poor prognosis in children with VE (<0.05).

Conclusions: The cerebrospinal fluid and serum levels of SIL-2R, eNOS, and CD93 are significantly elevated in children with VE, and they are associated with VE progression and prognosis.
